How do I use v-model with custom components in Vue 3?

In Vue 3, you can use v-model with custom components by defining a modelValue prop and emitting an update event.

Can you show me an example of a custom component using v-model?

Sure! Here's a simple example:

<template>
  <input :value="modelValue" @input="$emit('update:modelValue', $event.target.value)" />
</template>
<script>
export default {
  props: ['modelValue'],
};
</script>

What if I want to use multiple v-models in one component?

You can use multiple v-models by defining additional props and emitting corresponding update events for each.

Are there any best practices for using v-model with custom components?

Yes, keep your props and events consistent, and ensure that your component is reactive to changes in the modelValue.
